After few minutes ada1 become 99% busy (ada0 was busy at 33%), MB/s lowered from 255 Mb/s (sata2 controller used on this machine) to 85 MB/s. dd was stopped when file /mnt/1.tst reached 190G size. And finally umount /mnt fsck_ffs -E -d /dev/mirror/gm0 I could not reproduce the problem when fsck_ufs run more than 6 minutes. --=20 You are receiving this mail because: You are the assignee for the bug.=
